To have a glimpse of what Leela sees ahead, a speculative one following the PV:

After 8 moves, it's still in main theory:

It is played by many top players today. Its performance among 2700+ players from my database is:
Players average: 2761
Performance: 2815
White Win: 22.1%
Draw: 66.2%
Black Win: 11.7%
========================
Overall performance: 55.2%
Although the draw rate is very high (66.2% compared to 52.4% from the starting position), White Win/Loss ratio is among the highest (almost 2) of the opening repertoire. According to Lc0, Black cannot defend better against e2e4.

It is soon out of general theory (Catalan Opening, General), but after 6 moves it's still played by many top players today, and it seems not that rare among top players (maybe a new trend?)

Its performance among 2700+ players from my database is:
Players average: 2752
Performance: 2775
White Win: 22.2%
Draw: 60.4%
Black Win: 17.4%
========================
Overall performance: 52.4%
The draw rate is somewhat lower here (still pretty high), but the White performance is not that good, too many Black wins. According to Lc0, White cannot do better with d2d4.
============================
Is it all due to some simple or stupid peculiarities of Lc0, this net, some tactics or something like that?
